H EA D REST.

SPECIPICATION forming part of Letters Patent No. 357,305, dated February 8, 1887.

I Application filed July 29, 1886. Serial No. 209.459. (No model.) i

residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Head- Rests; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1 r a Our invention relates to an improved headrest adapted to use on chairs, car-seats, &c.

The object of the invention is to obtain a simple and comfortable head-rest which is portable and adapted to use on a variety of styles of seats.

To the accomplishment of the above theinvention. consists of certain novel devices and combination of devices, as will be described and claimed.

In the accompanying drawings, to which reference will be made, Figure 1 is a front elevation of the device complete; Fig. 2, a rear elevation thereof; Fig. 3, a side view showing by dotted lines the different positions; Figs. 4, 5, and 6, details of parts.

Like letters refer to like parts in each view.

The invention consists of two essential parts,- to wit, the head-rest proper, together with its attachments, and the means for holding it in position upon the seat. We provide a roll or cylindrical block, A, around which a spring-wire, B, is coiled. By reference to the drawings it will be seen that this wire is bent at its center to form nearly a complete circle, and that each arm of said wire thus formed is coiled around block A near each end of said block, and then carried back nearly to the point of commencement. We prefer to coil the wire three times around the block, as shown, and by the construction thus far described, we obtain means for holding the rest firmly on the back of the seat, the two arms of the wire resting against the back of said seat, and that portion thereof first referred to pressing against the front face of said seat, as shown in Fig. 3.

For the head-rest we employ a frame, 0, consisting of two uprights and an upper crosspiece. Each lower end of the uprights is coiled around the outer end of block A and bent at its ends, as shown at b in Figs. 1 and 2, these bent ends being adapted to engage with a bend, a, Fig. 3, formed in each arm of the wire'B, and thus serving to prevent the frame 0, which carries the head-rest, falling back beyond a certain point.

D represents a third frame-work, preferably of wire, which may be bent to any suitable curve or outline to suit the head, the same being shown in dotted lines in Fig. 3, and consisting'of two uprights and an upper-crossbar. The lower end of each upright is formed into a coil, 1), which surrounds each an upright of frame 0, and each of which coils ends in an arm or point, 0.

Mounted upon each upright of frame 0 is an inverted-V-shaped arm, E, the short arm of which is perforated and passed around the arm or point 0. Between arm E and coil 1) there is a spiral spring, F, the pressure of which serves toforce arm E into such a position that the upright of frame 0 will pass therethrough infan oblique manner, and thereby prevent the lowering of the frame D until suitable pressure is brought to bear upon arm E to bring it at right angles to the-upright, when the frame D can be lowered.

' The frame D is covered with any suitable material, G. which is stretched thereupon and laced at the rear, as shown.

What we claim is- 1. In a head-rest of the character described, the combination, with the blockA and wire B, wound thereon and terminating in bend a, of the frame 0, provided with the rest D G, adjusted by means of the clamp E, substantially as set forth. 7

2. In a head-rest of the character described, the combination, with upright frame 0 and the head-rest proper, D G, sliding thereon, of the bent and perforated clamp-arm E and the spring F, as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
